CLLOMAGY 3/4-Inch Pin Post, 6-Inch Height
Best for: small to mid-size boats needing a compact lift without complex installation. This 3/4″ pin post fits most 7″ x 7″ bases and provides a 6″ height. The lock-in design secures the seat against detachment during movement, making it a strong starter option for pontoon or bass boats.

Best for: boaters who want a non-threaded, lock-in option with multiple height choices. This post is available in several heights (6″, 11″, 13″, 16″), though the 6″ version is a focused choice for standard setups and quick seat changes.
Why selected: secure lock-in design reduces seat movement; standard 3/4″ diameter ensures broad compatibility. Caution: verify base compatibility and select the correct height to avoid overly tall or short seating.
Attwood SP-28913 Wedge 2-Inch Extension Post
Best for: boats needing a longer reach with a wedge mounting system; the 2-inch wedge design fits a variety of fixed-height seat bases and adds significant height for tall decks.
Why selected: designed to fit pre-1998 Mercury/Mariner-style engines and features a sprayless connector for safety during hose connections, which is beneficial for boats with integrated fuel systems. Caution: not all bases are compatible with wedge extensions; confirm base type before buying.
Attwood Adjustable Height Post, 13–19 Inches
Best for: boats that require a customizable seating height for different crew members, pilots, or anglers. The post slides from 13″ to 19″, offering flexible comfort across varied seating positions.

Best for: boaters needing a mid-range lift with a secure wedge mounting system. The 11″ extension provides comfortable seating height for many deck layouts.
Why selected: sturdy, aluminum construction with satin finish; the wedge system helps lock the post into the base to prevent detachment. Caution: ensure the wedge base is compatible with your specific pedestal base design.
Buying Guide
What height should I choose?
Consider the typical seating position from your helm or fishing chair. Shorter heights (6–10 inches) suit compact boats or low decks, while mid- to tall-range extensions (11–19 inches) suit elevated seating or tall crew members. Fixed-height options are simpler, while adjustable posts offer flexibility across trips.
What mounting style matters?
Lock-in pin posts are quick to install and less likely to detach. Wedge extensions provide strong engagement into wedge bases but require compatible base designs. Non-threaded vs threaded posts impact compatibility with existing bases—verify diameter and base type before purchase.
Material and finish considerations
Look for marine-grade aluminum with satin or hard anodized finishes for corrosion resistance in saltwater environments. A smooth-release mechanism reduces effort when adjusting or removing the post.
Compatibility and boat type
Most 7″ × 7″ pedestal bases are compatible with 3/4″ diameter posts and standard lock-in mounts. Pontoon, bass, and jon boats commonly use these bases; always confirm base dimensions and pin type before buying.
Safety and maintenance
Check locking mechanisms for signs of wear. Regularly inspect pins, latches, and wedges for corrosion or deformation. Replace worn parts to prevent seat detachment during motion.
